For the lag, my guess is that your hands-free device is downloading your phone book and call logs. My Kenwood DNX8120 does that, and while it is downloading the phone slows to a crawl. Once it is done downloading those, the phone should return to normal speed. I think it may be because of the sheer number of call logs that I have, and I'm trying to find a good way to prune the really old stuff out.
